Comment:

 Minimal fix:

 https://github.com/special/tor/compare/bug15823

 I haven't actually reproduced this case to test it so far.

 I think we should also reject INTRODUCE2 cells with an unknown auth_type,
 instead of assuming we understand how to use them, but that would be a
 separate patch.
